Dummies has always stood for taking on complex concepts and making them easy to understand. Dummies helps everyone be more knowledgeable and confident in applying what they know. Whether it’s to pass that big test, qualify for that big promotion or even master that cooking technique; people who rely on dummies, rely on it to learn the critical skills and relevant information necessary for success.

Keep a close eye on the temperature and moisture level of the soil to keep the seed happy. It’s very delicate at this stage. Use a spray bottle to water it—over-watering can suffocate and kill the delicate sprout.
Pre-flowers can initially be extremely small and hard to identify with the naked eye, but you can use a magnifying glass to get a better look.
Because training happens during vegetative growth, for autoflowering plants, this period could be as short as a few weeks, which means time is limited. Try topping your autoflowers after they have three nodes, and stop once they begin to flower. You will want to prune them lightly.
Most cannabis plants begin flowering when the amount of light they receive on a daily basis reduces. Outdoors, this happens when the sun starts setting earlier in the day as the season turns from summer to autumn. Indoor growers can control when a plant flowers by reducing the daily amount of light plants receive from 18 hours to 12 hours.
If buying from a reputable breeder or seed bank, growing from seed is the best way to ensure your plants will have solid genetics and start clean, meaning they won’t come with diseases or pests.
Because only female cannabis plants produce buds and you want them to focus all their energy on producing buds and not seeds, it’s important to identify and get rid of male weed plants so they don’t pollinate females. If females are pollinated, it will give you buds filled with seeds, making your weed harsh and unpleasant.
So don’t discount bud because it has a seed or two in it. While not ideal, it could be the origins of the next great weed strain.
Outdoors the first stage of flowering can be seen when Summer’s heat has passed and autumn approaches. Indoors you control when the flowering begins by changing the lighting schedule to a twelve hour day, twelve hour night photoperiod.
HUMIDITY: Outdoors you don’t really have any control over this factor and you are at the mercy of your climate. The upside is that the variations in humidity and the robust biological functions needed to adapt to a changing grow environment makes your plants exceptionally strong!
Beginning your whole cannabis grow adventure is the germination of your seeds. Each viable seed contains all the information needed to grow the strain of plant you have chosen. All they need are the right conditions and the life cycle will begin. Seeds won’t germinate until three specific needs are met. Water, correct temperature (warmth) and a good location.
How Long Does The Vegetation Phase Last?
IN WATER: Simply soak seeds in enzyme enriched water until you see the tap root appear then put in your medium. The seedling will quickly strike and break the surface about a week later.
TEMPERATURE: Cannabis is a very hardy plant and can survive cold and heat well. Just like you or me though, it can get stressed and not function well in the extremes. Cannabis can freeze or boil to death. It can stop growing or go into stasis. It will go into survival mode if the temperatures are too high or too cold for too long. Twenty-seven degrees centigrade is the accepted ideal for vigorous cannabis growth. Indoors this is easy to achieve with fans, air conditioning units, heating and cooling mats. Lights will certainly generate heat that needs to be vented.
STRAIGHT INTO THE MEDIUM: Place seeds directly into your medium, this way you can avoid any transplant shock. More often it is easier to germinate in a small pot of your chosen medium then pot on to the garden or bigger pots.
Legal cannabis is becoming the norm across the United States and in many other countries of the world. Hooray!! Although not official, it is ostensibly legal in most of Europe and if not legal, then certainly tolerated.
